Pancreatitis caused by duodenal duplication.

The authors present the investigations and surgical treatment of two cases of duodenal cystic duplication. Abdominal pain and gastroesophageal reflux were the most important symptoms and signs associated with an history of recurrent acute pancreatitis. Computed tomography scan, ultrasound examination, and cholangiography confirmed preoperatively the diagnosis, and a transduodenal surgical approach was carried out in both children. A simple marsupialization of the cyst was performed in the former, and a sphincterotomy with papillosphincteroplasty was associated in the latter. The diagnosis was confirmed by microscopy, and both the children are asymptomatic after a 14 and 18 months of follow-up. This report focuses on the importance of the cholangiopancreatography for every child presenting with recurrent, unexplained bouts of acute pancreatitis, and underlines the technical surgical aspects on the basis of the anatomic identification of the malformation.

[Intraparenchymal renal Doppler: the indirect signs of renal artery stenosis in native and transplanted kidneys in childhood].

Ultrasonography is currently the method of choice to examine the pediatric patient because it is widely available, noninvasive and inexpensive. Particularly, Doppler US is the method of choice to study renal artery stenoses, which are among the most frequent causes of arterial hypertension in children, in both renal allografts and native kidneys. This study was aimed at investigating the value of the indirect signs of stenosis observed during the assessment of intrarenal vessels--i.e., changes in the waveform, resistive index and acceleration index. We examined 63 renal allograft recipients and a 12-year-old boy with a native kidney and arterial hypertension. In all cases the Doppler curves of the intrarenal vessels were studied both qualitatively and quantitatively. In this paper we report on 5 cases (4 allografts and 1 native kidney) with major waveform changes in the downstream renal circulation. Our findings confirmed the resistive index and the acceleration index measured with Doppler US in the intrarenal vessels to be major diagnostic tools in renal artery stenoses in the pediatric patient when the renal arteries are difficult to assess. However, the technique exhibits some limitations and allows an unquestionable diagnosis only in severe stenoses.

[Non-Hodgkin's lymphoma with hepatosplenic involvement. The importance of imaging diagnosis using magnetic resonance tomography].

This study evaluates the importance of magnetic resonance imaging (MR) in the exploration of the abdomen in a case of non-Hodgkin lymphoma diagnosed in a 14-year-old boy. Results are compared with those obtained using two widely used diagnostic methods: CT and ultrasonography (US). US revealed a prevalent involvement of the spleen, whereas CT showed a marked hepatic infiltration. The role of MR seems important because it allowed the contemporary and careful evaluation of hepatolienal involvement. The main advantages and drawbacks of using MR in pediatrics, and in particular in the study of the metastatic involvement of hypochondriac organs are discussed.

[Treatment of pilonidal sinus. Our experience].

The various types of surgical techniques adopted in a group of 167 patients suffering from pilonidal cysts and fistulas are examined: closed, semi-closed and open method. The results are assessed and the reasons for preferring the closed method are examined.
